Description

Technical Field

[0001] This utility model relates to the technical field of engineering auxiliary equipment, and in particular to a transport vehicle that is easy to turn. Background Technology

[0002] Existing construction site transport vehicles are typically designed to run on tracks to improve the efficiency and safety of material transport. These vehicles are equipped with bogies to support the car body and allow for flexible steering on the tracks. Bogies generally consist of complex mechanical structures, including wheelsets, frames, suspension systems, and traction devices. These components work together to ensure the transport vehicle can smoothly navigate curves and uneven tracks. However, this complex design also brings significant drawbacks: firstly, the manufacturing process of bogies requires extremely high precision machining and assembly, leading to a substantial increase in production costs; secondly, their maintenance is difficult, requiring regular professional inspections, further increasing operating costs. Therefore, although bogies improve the performance of transport vehicles, their high cost and maintenance expenses are a major factor limiting their widespread application. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where rail transport vehicles are equipped with bogies, but the bogies have complex structures and high costs, which is not conducive to saving construction costs, and to provide a transport vehicle that is easy to turn.

[0004] In a first aspect, the present invention provides a transport vehicle that is easy to turn, comprising:

[0005] The frame has adjusting wheels on its upper surface, and the axles of the adjusting wheels are arranged along the front-rear direction of the transport vehicle.

[0006] A support pad is provided above the adjusting wheel. The support pad is used to support the object to be transported. The position of the support pad can be adjusted along both sides of the transport vehicle by the adjusting wheel.

[0007] A walking device is provided below the frame, and the axis of rotation of the walking device is perpendicular to the axis of rotation of the adjusting wheel.

[0008] The adjusting wheel's axle is positioned along the front-to-back direction of the transport vehicle, and a support pad is positioned above the adjusting wheel. When the transport vehicle turns, the support pad is adjusted towards the center of the curve, thereby causing the object to be transported on the support pad to adjust towards the center of the curve. This shifts the overall center of gravity of the transport vehicle towards the center of the curve, facilitating turning. Compared to existing transport vehicles that use bogies for easier turning, this application only requires adjusting wheels with axles along the front-to-back direction of the transport vehicle on the frame. Adjusting the center of gravity during turning makes turning easier. This transport vehicle has a simple structure, low cost, and helps save on construction costs.

[0009] Preferably, the shaft of the adjusting wheel is rotatably connected to the frame.

[0010] The adjusting wheel's shaft is rotatably connected to the frame, minimizing the possibility of the adjusting wheel detaching from the frame, thus improving structural integrity and extending the structure's service life.

[0011] Preferably, the frame is further provided with an adjustment platform, the adjustment wheel is disposed on the adjustment platform, and the width of the adjustment platform is greater than the width of the adjustment wheel.

[0012] An adjustment platform is set on the frame, and the adjustment wheels are set on the adjustment platform to rotate. The structure is simple and easy to manufacture.

[0013] Preferably, a blocking member is provided on the side of the adjustment platform, the blocking member being used to prevent the adjustment wheel from detaching from the adjustment platform.

[0014] The adjustment platform has a barrier on its side to prevent it from detaching from the frame as much as possible.

[0015] Preferably, the frame is further provided with a first limiting member, which is used to limit the maximum displacement of the supporting pad in the front-rear direction of the transport vehicle.

[0016] During transportation, the object to be transported has inertia. When the transport vehicle starts or brakes, the object to be transported will move towards the rear or front of the transport vehicle. The first limiting device is set to prevent the object to be transported from leaving the transport vehicle.

[0017] Preferably, the first limiting member comprises at least two, wherein the two first limiting members are respectively disposed on the foremost and rearmost sides of the upper surface of the transport vehicle.

[0018] By setting a first limiting component at the frontmost and rearmost sides of the upper surface of the transport vehicle, the object to be transported can be prevented from falling off the transport vehicle as much as possible without affecting the load capacity of the transport vehicle.

[0019] Preferably, the frame is further provided with a second limiting member, which is used to limit the maximum displacement of the supporting pad along both sides of the transport vehicle.

[0020] A second limiting component is installed to restrict the maximum displacement of the supporting pad along both sides of the transport vehicle, so as to avoid the supporting pad from detaching from the transport vehicle when adjusting the overall center of gravity of the transport vehicle.

[0021] Preferably, the supporting pad is provided with a through hole, the width direction of which is along both sides of the transport vehicle, and the second limiting member extends into the through hole.

[0022] By inserting the second limiting member into the through hole, compared to placing the second limiting member on both sides of the transport vehicle, it is possible to minimize interference with the surrounding environment during transportation and require less space for transportation.

[0023] Preferably, the walking device is a walking roller, and the walking roller has a rim on its outside.

[0024] The traveling rollers are equipped with flanges to accommodate rail transport. Furthermore, placing the flanges on the outside of the traveling rollers helps reduce the interference of road debris with the internal space of the frame, thus improving the stability of the transport vehicle.

[0025] Preferably, an insulating gasket is provided inside the rim.

[0026] Insulating gaskets are installed inside the wheel flange to minimize friction between the inside of the flange and the track, thus preventing the transport vehicle from affecting its operation.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] This utility model provides a transport vehicle that facilitates turning, comprising a frame, supporting pads, and a traveling device. Adjusting wheels are provided on the upper surface of the frame, with the axles of the adjusting wheels positioned along the longitudinal direction of the transport vehicle. The supporting pads are positioned above the adjusting wheels. When the transport vehicle turns, the supporting pads are adjusted towards the center of the curve, thereby causing the object to be transported on the supporting pads to move towards the center of the curve. This shifts the overall center of gravity of the transport vehicle towards the center of the curve, facilitating turning. Compared to existing transport vehicles that use bogies for easy turning, this application only requires adjusting wheels with axles on the frame along the longitudinal direction of the transport vehicle. Adjusting the center of gravity during turning makes turning easier. This transport vehicle has a simple structure, low cost, and saves on construction costs. This application overcomes the shortcomings of existing rail-mounted transport vehicles with bogies, which have complex structures and high costs, hindering cost savings in construction.

[0038] Example 1

[0039] like Figures 1 to 2 As shown, a transport vehicle that is easy to turn includes:

[0040] The frame 1 has an adjusting wheel 101 on its upper surface, and the axle of the adjusting wheel 101 is arranged along the front-rear direction of the transport vehicle.

[0041] Supporting pad 2 is disposed above adjusting wheel 101. The supporting pad 2 is used to support the object to be transported. The position of the supporting pad 2 can be adjusted along both sides of the transport vehicle by adjusting wheel 101.

[0042] The walking device 3 is located below the frame 1, and the axis of rotation of the walking device 3 is perpendicular to the axis of rotation of the adjusting wheel 101.

[0043] The adjusting wheel 101 has its axle positioned along the longitudinal direction of the transport vehicle, and the supporting pad 2 is positioned above the adjusting wheel 101. When the transport vehicle turns, the supporting pad 2 is adjusted towards the center of the curve, thereby causing the object to be transported on the supporting pad 2 to adjust towards the center of the curve. This allows the overall center of gravity of the transport vehicle to move towards the center of the curve, facilitating turning. Compared to existing transport vehicles that use bogies for easier turning, this application only requires adjusting the wheel 101 with its axle positioned along the longitudinal direction of the transport vehicle on the frame 1. Adjusting the center of gravity when the transport vehicle turns facilitates turning. This transport vehicle has a simple structure, low cost, and helps save on construction costs.

[0044] In one or more embodiments, the pivot of the adjusting wheel 101 is rotatably connected to the frame 1.

[0045] In one or more embodiments, the frame 1 is further provided with an adjustment platform 102, and the adjustment wheel 101 is disposed on the adjustment platform 102. The width of the adjustment platform 102 is greater than the width of the adjustment wheel 101. A blocking member 103 is provided on the side of the adjustment platform 102, and the blocking member 103 is used to prevent the adjustment wheel 101 from disengaging from the adjustment platform 102.

[0046] Furthermore, the frame 1 is also provided with a first limiting member 4, which is used to limit the maximum displacement of the supporting pad 2 along the front-rear direction of the transport vehicle. In this embodiment, there are at least two first limiting members 4, wherein the two first limiting members 4 are respectively disposed on the foremost and rearmost sides of the upper surface of the transport vehicle.

[0047] Furthermore, the frame 1 is also provided with a second limiting member 5, which is used to limit the maximum displacement of the supporting pad 2 along both sides of the transport vehicle. In this embodiment, the supporting pad 2 is provided with a through hole 201, the width direction of the through hole 201 is along both sides of the transport vehicle, and the second limiting member 5 is disposed in the space between the traveling devices 3, extending into the through hole 201.

[0048] Furthermore, the walking device 3 is a walking roller, and the walking roller is provided with a rim 301 on its outside. An insulating pad is provided inside the rim 301.

[0049] In practical use, when there are many goods to be transported, several transport vehicles can be used in coordination. For example... Figure 2 As shown, two transport vehicles are used to transport multiple railway sleepers 6. A connecting piece 7 (in this embodiment, a rail) is installed above the supporting pads 2 of the two transport vehicles to raise the sleepers 6, facilitating subsequent hoisting. Sufficient distance is maintained at both ends of the transport vehicles to prevent the sleepers 6 from detaching. However, it is necessary to ensure that the top surface of the supporting pad is higher than the top surface of the first limiting member 4 to meet the requirements for adjusting the center of gravity.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
